SPECIFICATION forming partof Letters PatentNo. 593,855, dated November 16, 1897. Application filed May 13, 1897. Elerial No. 636,343. (No model.)

To all whom, it may concern:

Be it knownthat we, LoUIs PROLL, CHARLES M..DEPEW, and EUGENE W. HAWLEY, citizens of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Reversible Windows; and We hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to an attachment for Windows by which we are enabled to turn or reverse the sashes about pivots centrally dis posed in'opposite sides, so that the windows may be turned at right angles with the line in which they ordinarily slide.

It consists in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a general view of the window. Fig. 2 is a vertical section through one side of casing and sash on line 5 z of Fig. 4. Fig. 3 is a top view of the lower sash, showing the locking device. Fig. 4: is a horizontal section on line x at, Fig. 2. Fig. 5 is a similar section on line y y, Fig. 2. Figs. 6 and 7 show the arrangement of suspending the weight by chains.

In the construction of our device the sashes A, which are slidable with relation to the easing B of the window, are made of such a width from side to side as to allow them to turn between the parting-strips b of the oasingsB.

C is a groove or channel by which the sashes A are guided, and D are slides of a width equal to the thickness of the sash, having a length corresponding with that of the sash and adapted to slide in .the grooves or channels C. To these slides the sashes A are pivoted at about the center by pivot-pins E, and as the sashesare no wider than the distance between the parting-strips b (the slides D filling the depths of the channels 0) it will be understood that thesashes may when free be turned about their pivot-pins E, so as to stand at any desired angle, or be reversed to expose the outer. surfaces to the interior.

with channels F, extending vertically, and cor In orderto lock the sashes A to the sliding pieces D, we have shown the slides formed and slides together.

responding channels are made in the sashes. Within these channels in the sashes are fitted strips Gr, preferably of metal and of a thickness which will allow them to be moved into the slots F in the slides D, so that when in this position the sashes and the slides D will be locked together and will then be slidable up and down in the channels in the casing in the manner of any ordinary window. When the strips G are moved into the sash, so as to be disengaged from the sliding pieces D, the sashes will then be-free to turn about their pivot-pins E, as previously described. These strips G have inclined slots H made in them, and these slots fit over pins I, which are fixed in the sashes, so that when the strips G are moved upwardly they will slide at the same time inwardly, by reason of the inclination of theslots H, until they lie entirely Within the sashes, thus allowing the latter to be turned when thus released. WVhen the strips G are again moved outwardly and downwardly, the outer edges of the strips G enter have shown short lever-arms J fulcrumed or V pivoted to the sashes, as shown at K, so that the outer ends project within reach of the operator, while the inner ends engage grooves or channels L in the strips G. It will be seen by this construction that the strips G will normally slide downwardly and outwardly upon the pins I by reason of the diagonal position of the slots H, and the outer edges of the strips will engage the channels F in the sliding pieces D and thus hold thesash When it is desired to turn the window, it is only necessary to press upon the two thumb-pieces'J upon opposite sides of the sash, when the strips G will be raised and by reason of :the inclined slots drawn into the sash at the same time, so as to leave the latter free to turn aboutits pivotpins E. V

J are projections fixed just below the lever-arms J, which enable the operator to grasp both between the thumb and fingers and thus exercise the necessary pressure to operatethe levers J and diserigagethe strips I00 G. Then the sash is restored to its normal position, the strips G will 1 naturally drop into the-slots in theslides D.

The sliding pieces D, to which the sashes 5 are pivoted, may be connected with the counterbalance-weights by means of a cord or chain 0. hen the cordisused an eye or loop maybe formed at the end opposite to, that to which the weight is attached, and this loop is slipped over a cylindrical projection P, which has a flange P upon the out-1 side, this flange and the cylindrical portion being countersunk into the slide D and secured by screws or otherwise. The pivot-pins E form extensions from the center of the part P, and theirinneriends project into socket-pieces upon which the sashes turn, as previously described.

:In somescases chains are used in place of the cords; i-n-awhich casev an i extension P is inadezfrom the. upper: part of the cylindrical"v portion P,:having-a transversechannel made. .in it, :asshown at R.
